X squared is first year, most part by their second. We're goingto port side effects is one of our spirit for months. Expert. So these will cancel out, and we will find a way to permit tax as, um, off your shoes can slap negative X divided by skirted off one one's expert times Art Sina Bucks plus one. The few graft, Equifax and private fax where this record is perfect and it's blue ones that prime effects you could use another function porter. We see that it makes sense because whenever function goes from decreasing to increasing the they're interchanges sign and it goes from negative 2002. Also same behavior.
